ABSTRACT:
Provided is a liquid crystal display device including a pair of transparent substrates opposing each other, and a frame-like shaped sealant layer with an opening which serves as a liquid crystal introduction inlet. The sealant layer-is provided between the pair of transparent substrates and around their overall periphery spaced apart by a predetermined distance from the peripheral edge of transparent substrates. The pair of transparent substrates are bonded to each other by the sealant layer so as to be held at a predetermined distance therebetween. A liquid crystal material is sealed in between the pair of transparent substrates, and a pair of liquid-crystal-elevation stoppers respectively formed between the pair of transparent substrates and on both sides of the liquid crystal introduction inlet so as to be coplanar with or squeezing out of (i.e., projected from) the peripheral edge.
